I have a hard copy of this book (bought it years ago) but it's good to have the additional resource online so I don't have to lug the book around. Blender has changed a little bit between 2.3 and the current 2.4x, but I've been able to follow it so far.

I suspect you could find something similar for other 3D applications as well. I only bring it up because Sketchup is very easy to model in, although it does get clunky once your model gets fairly detailed.

While looking around for information about the DarkPlaces model format I stumbled on a lengthy tutorial today from Kot-in-Action detailing how to convert Blender files into .DPMs

Also, leileilol had sent me a few links last year, about getting blender models converted to md3 last year... which I have yet to try.

Looks like Blender 2.5 is coming along well. I've been putting off doing much with Blender in general because of the UI changes and worries about stability, but I figure that by the time I actually get used to using the 2.5 alpha, they will have released the final version. So...

For anyone else that's interested in "Blending"
• GraphicAll.org, has the latest Blender SVN builds for download.
• BlenderCookie, has some very nice intro to Blender videos that focus on the 2.5 UI
